sys9 brand.
The marks, colors, and type that make sys9 look like sys9. Monochrome, terminal-flavored, and quiet on purpose. Use these as-is — if you need source files, just ask.
Wordmark, app icon & display mark.
The wordmark is set in JetBrains Mono, heavy weight. sys sits at full strength; the 9 steps back in muted gray. The compact app icon uses s9; a standalone 9 can be used as a display mark.
s9 app icon Neutral palettes for dark and light.
The core interface uses neutral grays in both themes. Green communicates success or availability; red communicates errors. These semantic colors support status, while the marks remain monochrome.

Do
Write the name as sys9, lowercase, one word. Use the bare CLI names (db9, run9) for the tools. Keep generous clear space around the mark. Use the theme-appropriate foreground on a clean dark or light background with sufficient contrast.
Don't
Don't capitalize as “Sys9” or “SYS9”, don't add color or gradients, don't put the mark on busy or low-contrast backgrounds, and don't stretch the marks.
